This looks amazing. I'm not entirely sure if I, personally, have any use for this, but such basic, simple, handsfree information could be invaluable to, for instance, construction workers, farmers, police officers, or other people who do hard, dangerous work with their hands.

You know, I am not happy that we've created an incentive to hide information in the first place. At some point we as a society should consider ditching the notion that having information is cheating and instead encourage it as a legitimate tool to advance human capacity. Instead of grading us in an information void without tools & material, education should try and find ways to keep students challenged with technology. Rather than training our brains to do tedious repetitive tasks, we could focus on higher level abstractions and maximize our benefit from computers. If traditional classwork becomes too trivial with technology, then maybe classwork itself needs to evolve.

It's just a thought, maybe one day not allowing technology on tests will be considered Luddite
